Local lawmakers Thursday introduced an amendment to financial reform that would allow depositors at failed Pasadena-based Indymac Bank to recoup a collective $233 million in lost savings.

The amendment, called the Indy Act, would make a federal deposit insurance cap of $250,000 retroactive to the time IndyMac failed in July of 2008. At the time, deposit insurance was set for deposits up to $100,000. But as the financial crisis grew Congress only a few months later approved the heightened cap.

But the cap did not extend to institutions that failed before October 2008.

“The whole thing is about fairness,” said Rep. David Dreier, R-San Dimas, who along with Rep. Jane Harman, D-Venice, introduced the bill Thursday.
